HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The correct option is Option A

There is a negative association because in general, as hot chocolate sales increase, ice cream sales decrease.

Step-by-step explanation:

We need to identify the association between the hot chocolate and ice cream sales.

Looking at the graph we observe that,

if sales of hot-chocolate are $50

then sales of ice cream are $95

if sales of hot-chocolate are $70

then sales of ice cream are $85

if sales of hot-chocolate are $95

then sales of ice cream are $60

So, from observation we can say that, if sales of hot chocolate are increasing then the sales of ice cream is decreasing.

It is known as negative association i.e, if one item is increasing then other item is decreasing

The correct option is Option A

There is a negative association because in general, as hot chocolate sales increase, ice cream sales decrease.

0.039 in scientific notation
Zielflug [23.3K]

Answer:

3.9 * 10^-2

Step-by-step explanation:

We need a number between 0 and 10, so we need to multiply.

0.039 * 10 = 0.39

0.39 * 10 = 3.9

Since 0.039 is less than 0, we are going to have a negative exponent.

3.9 * 10^-2

Best of Luck!
